请问一下,我在尝试用cloudstack的API与EC2相连,我已经按apache的document上步骤完成配置,也export了变量,但是当我用阅览器登陆端口时,总是有这样的错误:

<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope";>

<soapenv:Text xml:lang="en-US">

The endpoint reference (EPR) for the Operation not found is /awsapi/services/AmazonEC2/?command=ec2-describe-group and the WSA Action = null

</soapenv:Text>

</soapenv:Reason>

请问怎么解决啊?

谢谢
